Within the tray 5 I provide a plurality of grids comprising intersectingstrips 7 and 8 adapted to form squares within which cubes of ice may befrozen. In order that a- 5 large number of cubes may be made in the onetray, I provide spacing plates 9 between the grids so that each gridbecomes in effect a separate tray for freezing separate cubes of ice.
